 |
|
Hi there. People keep on telling me that I can right-click a file and then
go Sendto>>Compressed (zipped) folder and that will compress my file.
However, when I do this, the file is compressed from 8.38MB to 8.33MB, which
to me doesn't seem like a significant difference. when I use Winzip as
opposed to the Windows compression utility (I guess that's what it's called
when Windows does it for you by the abovementioned procedure) the same thing
happens: 8.38 to 8.33. Why aren't these compression services making my files
significantly smaller and which one is the best of the two?

Since both applications use the same algorithm, there is no difference.
In general, trying to compress executable files (*.exe, *.dll) or
graphic files being already compressed (*.jpg) is just a bad bargain.
Try to compress a bitmap file (*.bmp) instead in order to see the
reduction of size.

It depends on what the file type is. Some are already compressed, for
example .jpg and some certain video formats, so you won't see much change,
in fact in some cases the size will actually increase. So what kind of file
is this.?

This is a clue that the files are already compressed.
Think about it... if you could further compress and already compressed file,
the ultimate file size would be one byte. |
